I think Balloon Fight is a lot of fun, and Wrecking Crew is also pretty good. Ice Climber is okay, but the jumping is pretty sloppy. D.K. Jr. is ruined with terrible jumping. Yoshi is just boring. NES Open Tournament Golf is pretty deep for an NES sports game, but the super fast meter return makes it extremely hard to hit the ball with any kind of accuracy. Zelda will probably be more interesting once I get going, but so far I can't find anything to do except fight enemies for rupees until I have enough to buy something in one of the two shops I've found. I haven't tried Zelda II yet.

I've already got Super Mario Bros. and Metroid on the Wii's VC, so I already know what to expect with those.

So how large is the NES screen on the 3DS? Do you get to choose from large & Blurry, or Tiny Wrist Watch screen with Sharp graphics?lol I'm too lazy to whip open my 3DS right now and find out for myself hehe.

I was really surprised by balloon fight and Yoshi. I like Zelda II but it's really hard for me. Ice climber has problems with jumping. I've already played Zero Mission so Metroid isn't all that fun. Donkey Kong Junior is too slow. Open Gold is great once I find out how to hit properly. Super Mario Bros is....Super Mario Bros and I already own Legend of Zelda. So I like about half the games I got.

Yoshi turned out to be surprisingly fun once I figured out what I was doing. I started out just matching pairs and it seemed like the most boring game on earth. Then I got the whole "fill the eggs with bad guys" thing. Shooting to fill the eggs with as many dudes as possible, and kicking the speed up to high makes for a fun challenge. It's a solid little puzzle game.

Balloon Fight is one my favorites of the bunch. It's just a gleefully bizarre game. The music sounds like R2D2 on acid, and there's an undeniable sense of satisfaction in popping your opponents balloons and watching them pathetically parachuting to the surface. Perfect for on the spot alleviation of retro withdrawals.

NES Open Golf is another I found myself strangely enjoying... although I have no idea why. It's so simple its almost relaxing, I guess.

Ice Climber is frustrating but fun.

Wrecking Crew is alright.

Donkey Kong Jr. sucks to put it plainly. I love Donkey Kong, but I've always been underwhelmed by Jr., even as a 5 year old. It's a crappy excuse for a sequel.

EDIT:I finally figured out what's going on with the display resolution. It turns out that the game screen is stretched horizontally by some 20-ish pixels, and that's what creates the (barely-noticeable-but-still-there) anti-aliasing artifacts. The vertical resolution is fine (240 pixels). My guess is that they did this slight horizontal stretching to maintain the same aspect ratio seen on a regular TV screen.

Honestly, I think they're all great. Even the ones that I thought would be stinkers turned out to be a lot of fun. Wrecking Crew is fantastic, and NES Open Tournament? A great precursor to the proper Mario Golf series. My least favorite thus far is surprisingly Ice Climber, but I really just haven't played it enough. The jumping is incredibly unintuitive for a Nintendo game. Yoshi, Balloon Fight and DK Jr are great pick-up-and-play games, especially the former, which I think deserves a lot more credit than it typically gets.Metroid is my favorite NES game; Super Mario Bros. is one of the greatest platformers of all time, if not the best; Legend of Zelda is a classic that has only gotten better with age and Zelda II is ridiculously under-rated--and its a much-needed game on the e-shop as its severely lacking in quality RPG's. There's a lot of necessary level-grinding early on with Zelda II, but I'm enjoying the process, as the combat is really satisfying once you get used to it. Not to mention the dungeons are more coherently designed than the first game.

Over all I could hardly be more satisfied with my 10 free games. Sure, they could have thrown in a few more obvious crowd-pleasers like Punch-Out!! and Super Mario Bros. 3 but I'm glad they gave us a few obscure titles; I certainly would have never played Wrecking Crew and Yoshi otherwise, and I've ended up enjoying them immensely.

Super Mario Bros.: A classic and the best game of the bunch.Wrecking Crew: A great game but it sure does get hard pretty fast. If I thought Phase 15 was hard, then I'd hate to see anything past Phase 50.Balloon Fight: Another great game. Sure it's just a Joust clone but it's way better. Balloon Trip is great too and it has great music.Ice Climbers: Like I said before, the controls ruin this one.Donkey Kong Jr.: Yet another good game. Better than NES Donkey Kong but not quite as good as arcade Donkey Kong.Yoshi: It's ok, but gets boring pretty fastNES Golf: Don't care much for this one.Metroid: Hate this one. The music's good but it's too confusing.Zelda: Don't like this one either. ALTTP and Link's Awakening are good but for some reason this one isn't.Zelda II: Haven't played much of this one but the side scrolling aspects seem cool.
